United States Patent APPARATUS FOR DISPENSING BEVERAGES John F. Wellekeus, Staten Island, N. Y.

Application July 19, 1951, Serial No. 237,513

17 Claims. (Cl. 14 1-88) This invention relat'es to apparatus for dispensing beverages or other edible fiuids from cans or the like sealed containers made of metal or other suitable puneturable material, and is especially adapted for coin actuation and pre-selection of one of a plurality of flavors or kinds of beverages or the like edible fluds.

Conventional beverage dispensers presently in wide use fall into three general classes: e

1. Those in which the ingredients (i. e. syrup and water) are stored in bulk and when dispensed are mixed in a cup.

2. Those in which the beverages are sealed in cans and the cans are dispensed and the beverage is consumed from the cans.

3. Those in which beverages are sealed in cans of relatively larger size (i. e. in bulk); the large cans being fed in register with a bulk reservoir tank into which the contents of the cans are successively emptied by opening successive cans as they reach the reservoir; and the beverage is dispensed from the storage tank or reservoir by means of a measuring valve.

In each of these types there are certain inherent disadvantages. In the first or bulk mix type the bulk containers for the syrup are opened to be filled and are therefore subject fo contamination; and the water is usually supplied from the tap and hence depends upon the condition of the general water supply at the particular locality. In the second or canned beverage type the beverages tend to settle in such cans as remain in the storage space for an appreciable time and hence those flavors which -do not move fast are often in an unpalatable state; the cans when delivered to the customer have to be opened by a separate manipulation; the contents are either drunk directly from the can or by means of a straw and the cans are carried away and hence their metallic constituent is not readily recoverable and is usually lost. In the third type or bulk-can type the open pouring from the bulk can to the storage reservoir or tank and the exposure of the beverage poured into the tank, due to the open top of the tank, subject the beverage to contamination. Additionally, this type has the inherent disadvantage of the measuring valve.

An object of the present invention is to provide a dispenser wherein all cans of liquid stored therein are agitated each time a can is removed.

Another object is to provide mechanism for opening a can automatically as a part of the cycle of operation of dispensing a drink from said can directly into a drinking receptacle.

Another object is to provide mechanism for opening and venting a can, pouring the contents into a cup (preferably a one-use paper cup automatically supplied) and preventing drip from the can.

Another object is to provide means for receiving empty cans and crushing them to a flat condition and discharging them into a suitable storage for removal and use as scrap metal.

Another object of the invention is to provide a machine of the character described in which a large quantity of cans of each of a plurality of flavors or kinds of drinks' may be stored, a can of desired flavor selected, discharged, opened, poured into a receptacle, and the empty can crushed and discharged, all automatically and sequentially as part of a single cycle of operation.

Other objects are to provide a thermal chamber for the cans, adapted to maintain the contents at a predetermined warm or cool temperature; the chamber being free from electrical switches therein: the actuating mechanism in large part being disposed exteriorly of the thermal chamber; ready access into the chamber being provided for loading; the cup supply being exterior to said chamber for ready accessibility and visible to the Customer; and the Operating mechanism for etlecting the over-all cycle of Operations being "unitized tor ease of manufacture and assembly and ready maintenance.

Further objects, advantages and features of the invention will be apparent from the following defailed description of a presently preferred form of the invention taken in connection with the accompanying drawings herenafter referred to and in which:

Fig. 1 is a front elevation showing a preferred form of the invention, with certain parts broken away;

Fig. 2 is a sectional View taken along the line 2-2 of Fig. 1 showing the general arrangement of the parts in side elevation;

Fig. 3 is a somewhat enlarged side elevational View of the supply magazine unit, as viewed from the left hand side of the machine;

Fig. 4 is a cross-sectional View taken substantially along the line 4-4 of Fig. 2 so as to show certain structure in plan view;

Fig. 5 is a sectional view taken along the line 5-5 of Fig. 4 showing certain details of the pivotal arrangement of trays forming a part of the supply magazine;

Figs. 6 and 7 are perspective views showing typical of theindividual fray units.

Fig. 8 is an enlarged side elevational view, partly in section, ot the lower end of the supply magazine and related dispensing and delivering mechanism associated therewith, taken from the left hand side of the device;

Fig. 9 is a plan view of the rear part of the mechanism shown in Fig. 8, illustrating further details of the dispensing and delivery mechanism associated with the supply magazine;

Fig. 10 is a cross-sectional View taken along the line 10--10 of Fig. 9;

Figs. 11 and 12 are rear elevational views showing certain parts of the gate control mechanism illustrated in Fig. 10 in two difierent positions of operation;

Fig. 13 is a View similar to Fig. 12 showing further details of looking mechanism actuated when no can is present to be disposed;

Fig. 14 is a sectional View taken along theline 14 14 of Fig. 8 showing certain of the actuating mechanism in front elevation;

Fig. 15 is a sectional view taken along the line 15-15 of Fig. 8 showing the parts of Fig. 14 in plan view;

Fig. 16 is an enlarged front elevational View of a part of the mechanism shown in Figs. 14 and 15 in conjunction with coin lock mechanism;

Fig. 17 is a side elevational view of the structure shown in Fig; 16;

Fig. 18 is a sectional view taken Fig. 17;

Fig. 19 is a perspective view showing further details of certain parts shown in Figs. 16 and '17;

Figs. 20, 21 and 22 are side elevational views of certain of the parts shown in Figs. 16 and 17 with the parts shown in different positions of operation;
